Similar reference characters designate similar parts in the difierentviews.

The vendin apparatus is provided with a casing 1, whic Y may be of anysuitable form and material, and which is shown as being rectangular, andwhich is provided at its front with a spring closed door 2, which nor.-.mally closes an opening through which the cups, containing the drinksdispensed, are taken b the purchasers, Figs. 2, 3 and 7.

The rout of the casing 1 has attached to it a coin receiving device 3,upon which a coin is deposited and forced by the purchaser into a coinchute 4, Fig- 2. The said coin receivin device may be of any usual type.designe for the purpose.

The front of the casing 1 has an opening 5 normally closed by a springdoor 6, at the inner side of the casing, for the reception of cups whichhave been emptied by the purchasers; said opening 5 discharges into achute 7, which in turn discharges into a large receptacle 8 in thecasing 1, which is adapted to hold surplus liquid, which may be spilledin the casing when a purchaser removes a filled cupthrough the opening9, normally closed by the door 2, Fig. 6.

The top of the casing 1 has a door 10 normally closing the upper endof alar e tank 11 adapted to hold ice, and in whic is located a coiled pipe12 through which carbonated water is adapted to flow.' In the tank 11 isdisposed a receptacle 13 adapted to hold the syrup which 1s to form oneof the drink ingredients, see Fig. 5.

* 29, which is supported-on a plate 30 mounted BEST AVAILABLE coi Thetop of the casing 1 has mounted on it a vertical tube 14, Figs. 1, 2 and6, through which the cups, one oi which is shown in Fig. 6, designatedby 15, are inserted in nested form into a cup receptacle 16 disposedvertically in the casing at the rear of the front side thereof;

The cup receptacle 16 is provided above its bottom with a cup feedindevice of usual t pe having ahorizonta ly reciprocative' ever 17, whichwhen forced rear wardly from the position shown in Fi 3, will drop a cup15 from the lower en of the pile of cups, held in the cup receptacle 16,onto the bottom of said receptacle, as shown in Fig. 6. When the lever17 is retracted to the position shown in Figs. 3 and 6, the nextsucceeding cup of the pile will be in position ready to be dropped whenthe lever is again forced rearwardly.

Any cup feeding device having such an operating lever will answer mypurpose, and as many of such type are on the market no detaileddescriptionof the same need be made.

The cup 15 when dropped will be directly at the rear of thedoor 2, andas the opening 9, which is normally closed by the door 2, communicateswith the interior of the cup receptacle 16, the purchaser can readilygemove the filled cup 15 through such opening 9.

A drain chute 19, which dischar es into the receptacle 8, is supportedby tie bottom of the-receptacle 16, the latter having a drain opening 20which discharges into the chute 19.

Attachedto the rear of the cup receptacle 16 is a funnel 21 the lowerend of whlch is disposedwithin the receptacle 16 in position'fordischarging into a cup 15.on the bottom of the cup receptacle 16." i

For receiving a measured drink and discharging it into the funnel 21,there is provided an open top drink receiving and dis' chargingreceptacle 22, which at its front is provided with a delivery spout 23adapted, when the receptacle 22 is tilted to the. discharge position,shown in Figs. 3 and 6, to empty the contents of the receptacle 22- intothe funnel 21.

As shown in Figs. 3 and 6, the drink receiving receptacle 22 is pivotedon a horizontal transverse pin 24 mounted in two lugs 25 on a tiltableframe 26, whichv in turn is pivoted on two horizontal pins 27 mountedinlugs 28 on a U shaped plate on. two horizontal transverse channel bars31, the ends of which are supported by opposite sides of the casing 1. eFastened to the frame 26 is one end of a'bar 32 one end of which isthreaded and has mounted on it a counter-balancing weight33, which isadjustable toward and from the frame '26, and which carries a set screw34 for securingthe weight 33 in its adjusted position. The weight 33 isadjusted to a position such that the outer end of the bar 32 will beswung upwardly when the proper amount for a drink has been deposited, aswill be described, into the drink receptacle 22,- at which time, bymeans hereinafter described, the discharge of syrup and carbonated waterinto the receptacle 22 will be shutoti', following which the receptacle22 will be tilted-so as to discharge the contents thereof through its 5out 23 into the funnel 21, and thence into is ie waiting on '15. emptiethe weight 33 will cause the bar 32 and frame 26 to swing back to theinitial position shown in Figs. 1, 3 and 6. The downward movement of theouter end of the bar 32 is limited b its contacting with a plate 35fastened to t 1e channel bars 31.

The upper end of the cup receiving tube 14 may be provided with aremovable cover 36, and the lower end of the coin chute 4 dischargesinto a coin'receptacle 37, Figs. 1,2 and 3.

The rear side of the casing l'may have a large opening 38 adapted topermit access to the-interior of the casing, and normally closed by adoor 39.

For supplying carbonated water as one of the ingredients of the drinksvended, one end of the coiled pipe 12, in the tank 11, is connected to apipe 40, Figs. 1 and 2, which is connectedby a usual type of coupling 41with the usual tank 42 containing carbonated water. and having the usualshutoff valve 43. By disconnecting the coupling 41, a newly filled tank42 may be exchanged for an empty one.

Connected to the other end of the coil pipe 12 is a conductor 44, whichincludes a valve casing 45, and which discharges into the top of thedrink receiving receptacle 22, Figs. 1, 2 and 3. i a J The valve casing45 has in it a rotary valve stem 46, which has attached to it a crank 47adapted when oscillated to open -and close the valve. The-crank 47 ispivoted to one end of a contractible and extensible coupling comprisinga plate 48, to which the crank 47 is pivoted, having slots through whichextend clamping screws 49 mounted m a plate50 which is loosely pivotedto a crank arm 51 fastened on a horizontal transverse rock shaft 52,Figs. 1 and 3, which is pivoted at its ends respectively on two pivotscrews 53 and 54 mounted respectively in two' plates 30 and 55, thelatter being mounted on a bracket 56 supported by the channel bars 31,see Figs. 1, 10 and 12. The loose pivoting of the plate. 50, permits thecrank 47 to freely oscillate.

The rock shaft 52 is oscillated by means-0f a crank 57 mounted thereonand having two \Vhen the receptacle 22 has cal BESTAVAILA arms 58 and59, wliiclrrespectively extend in different directions, and which areadapted to be consecutively engaged by a roller 66 mounted on a crankarm 61, fastened to a horizontal rotary shaft 62 mounted in the plate55, Figs. 10, 12 3 also.

The shaft 62 has secured to it a worm wheel-63 which meshes with arotary worm 64, which is secured to a horizontal driven rotary shaft 65,Figs. 12 and 13, which is mounted in the plate 55, and has secured to ita pulley wheel 66, which is connected by a belt 67 with a pulley wheel68, which is fastened to the armature shaft 69 of an electric motor 70.The motor 70 is mounted 3n a swinging plate 71 having one end pivoted toa bracket 72 having two upwardly extending arms respectively secured tothe channel bars 31, see 1 and 2.

The other end of the plate 71 is secured to the lower end of a coilspring 73, the upper end of which is fastened to one of the channel bars31. By this means of support, the weight of the motor retains anoperative tension on the belt 67.

For tilting the drink receiving receptacle 22 to the discharge position,shown in solid lines in Figs. 1, 3 and 6, it has secured to it an arm74, which is in the path of the roller 60. The receptacle 22 normallyassumes and retains the filling position, shown in dotted lines in Fig.6 by gravity. \Vhen the crank arm 61 has in its revolution, caused theroller 60 to consecutively engage the arms 58 and 59 ot' the rock shaft5:2, to oscillate the latter. the receptacle will have received anddischarged :1 drink. After leaving the arm 59, the roller 60 engages theunder side of the arm 'T-l and thereby tilts the receptacle 22 to thedischarge position. After the roller has passed from engagement with thearm 74. the receptacle 22 will automatically swing to the fillingposition, and the .weight 33 will cause the bar 32 to swing the frameupwardly, and with it the receptacle 22. These pa rtswill retain theselast named positions until the rock shaft 52 has been again oscillatedto eflect the discharge into the receptacle of another drink. \Vhen theroller 60 swings the arm 58 c0unterclocle wise. as viewed in Fig. 10,the valve stem 46 will be turned to the open position by means of thecrank arm' 51. plates 50 and 48 and crank 47, thus permitting carbonatedwater to be discharged thronglrthe conductor-pipe 44 into the receptacle22. I

\Vhen the rock shaft :32 is rocked clockwise. Fig. 10. by the continuedrevolution of the. crank arm 61 and roll-er .60, the valve stem 46 willbe turned to the closed pos tion.

The rotary shaft 62. crank arm 61 and roller 60 come to a rest, aswillbe hereinafter described, after the rock shaft has been rocked counterclockwise, as described, and

and 13. see Figs. 1 and are COP.

rocked comiter-clockwise, Fig. 10, the syrup ingredient is dischargedfrom the syrup containing tank 13, Fig. 5, into the receptacle and thecarbonated water begins to pass into the receptacle 22, as described.When suilicient carbonated water has passed into the receptacle 22 tocause the weight of the latter, the drink content thereof, and the frame26 to over balance the rod or bar 32 and the weight'33, the frame 26 andreceptacle 22 will lower, thus raising the bar 32 and weight 33 andholding them elevated until the receptacle 22 has been tilted and thedrink discharged therefrom into the waiting cup 15 on the bottom of thecup re ceptacle 16. 1

After the rock shaft counter-clockwise, Fig. 10, the motor circuit isbroken, at which the motor shaft 69 stops, and is stationary until theframe 26 and receptacle 22 lowers, as described, upon which an arm 75secured to the frame 26, Fig. 3

52 has been rocked and Fig. 11 causes the motor circuit to be againclosed, as will be described. At this time theshaft 62, and crank arm 61will have made a half revolution from the initial position, shown insolid lines in Fig. 10, and will be in the dottedposition shown in saidfigure, thus holding the arm 58 in the dotted position of Fig. 10.

ll'hen the arm 75 closes the motor circuit,

the motor effects the revolution of the shaft 62, so that the roller 60will engage the crank arm 59 and will thus rock the rock shaft clockwisecausing the valve stem 46 to turn to the closed position, thus shuttingoff the discharge of carbonated water. at

which time the discharge of syrup will have stopped.

Now will be described the mechanism for supplying the svrup to thereceptacle 22, by the rocking of the shaft 52 contiter-clockwise,

Fig. 10.

Referring to Figs. 1, 3, 5, 6, 8 and 9, 76 designates a conductor, theupper end of which is secured to the bottom of the tank 13, whichcontains the syrup, Figs. 1 and 5, the lower end of the conductor beingsecured to and discharging into a valve casing 77, Figs. 8 and 9. saidvalve casing having avertical cylindrical portion 78 in which isvertically reciprocative a piston valve 7t), which normally rests at thebottom of the ltlti ll i 4 3 and 6.

BEST AVAILABLE COPE plate 30. The bar 83 is pivoted to a link 85 theupper end of which is pivoted to the lower end'of the stem 80. The bar83 has a longitudinal slot 86 in which is slidably titted a pin 87secured to a crank arm 88,

which is secured on the rock shaft 52, Figs.

\Vhen the rock shaft 52 is rocked counterclockwise, from its initialposition the piston valve 7 9 will be forced upwardly, by the mechanismjust described. past a passage 89 in the casing 77, which passageinclines downwardly from the cylindrical portion 78, thus shutting oti'the flow of syrup from said cylindrical portion 78 to the passage 89.The lower end of the latter discharges into a vertical cylinder 90, theu per end of which is secured to the incline portion of the casing 77which contains the pas sage 89. i

Slidable on the cylinder 90 is a sleeve 91, to the periphery of whichare attached two arms 92 of a plate 93 on which is fastened a valve 94,which is adapted, as shown in Fig. 8, to seat against the lower end ofthe cylinder 90 to close the lower end of the latter.

of the arms To normally hold the valve 94 closed, there is provided asubstantially horizontal lever 95, Figs. 8 ahd 9, which at oneendcarries a weight 96, which is adjustable on the lever 95 to which itmay be secured in an ad justed position by a screw 97. The other end ofthe lever 95 has two arms 98 pivoted on a horizontal axis to aflink 99the upper end of which is pivoted. to, a ring 100, which encircles andis rigidly fastened to the cylinder 90. The outer ends 98 arerespectively disposed at opposite sides 'of the cylinder 90 andrespectively pass between two pairs of pins 100 extending laterally fromand respectively secured to opposite sides of the sleeve 91.

The valve stem 80 extends between the arms 98, and has fastened on it,below the arms 98, a vertically adjustable ring 101,

which carries a set screw 102 bywhich the ring is fastened on the rod'tothe position on which it may be adjusted.

\Vhen the va ve 79 is moved upwardly to the closed position, above thepassage 89, the stem 80 will cause the ring 101 to engage the loweredges of the arms 98, thereby' swinging the lever 95 to lift the weight96 and forcing the sleeve 91 downwardly, thus carrying the valve94'downwardlyto the open position, thereby discharging the syrup whichis in the cylinder 90 and in the easiug 77-below the valve 7 9. Thisaction will takeplace when the motor operated crank arm 61 "causes theroller 60 to engage the crank arm 58 and rock the rock shaft 52counter-clockwise, as before described.

When the erank 'arm 61 so rocks the rock shaft, the. latter will,through the crank arm plate 105 and 88, and mechanism connected with itand already described, lift the valve stem 80 and valve 7 9 to theclosed-position. i

lVhen the crank arm 61 again starts rcvolving, after the proper amountof drink material has been discharged into the receptacle 22, andengages the crank arm 59 to rock the rock shaft 52 clockwise, thelatter, through the mechanism already described and the crank arms 51and 88 attached to the rock shaft, will cause the valve stems 46 and 80to be moved to the closed positions respectively, Then, as alreadydescribed, the crank arm 61 through the roller 60 and arm 74: will tiltthe receptacle 22 to the discharge position, shown in solid lines inFig. 6, and also in Fig. 3.

In order that the cup releasing lever 17 may be moved rearwardly to dropa cup 15 onto the bottom of the cup receptacle 16, before the receptacle22 is tilted charge poistion, the lever 17 has attached to ita rod 103,Figs. 3 and 6, which is pivoted to a crank arm 104, to the rock shaft52. When the latter rocks counter-clockwise, Fig. 10, the lever 17 willhe swung to release and drop a cup 15, and

when the rock shaft 52 is rocked 1n the opposite direction, the lever 17will be swung so as to place the next succeeding cup in condition to bedropped upon the next rearward swinging of the lever 17, in any mannerusually performed by ordinary cup dropping mechanisms of this type.

The mechanism'which times and controls the opening and closing of themotor circuit, and consequently the rocking of the rock shaft 52 and thefunctions effected by it, will now be described.

Referring particu'larly'to Figs. 2, 3, 11 and 12, supported on the frontchannel bar 31, is a'vertical plate 105, which is parallel with theright side of the casing 1 and is disposed over the chute 7.

rotatable on a shouldered screw 106 mounted in said plate is a disk 107,which has a peripheral shoulder 10S dis osed so as to be engaged by aplate 109, which is pivoted on a shouldered screw 110 mounted in theplate 105, and which has fastened to it a spring 111, which is alsosecured to two screws 112 mounted in the plate 105. The tension of saidspring normally forces the plate .109 into engagement with the disk 107.The plate 109 has also secured to it a plate 113 the front end ofwhichextends into the coin chute 1 through an opening 114 in the rearside of said chute. Said plate 113 is adapted 'to be engaged by andswung downwardly with the plate 109 by a proper coin passing downwardlythrough the chute. said coin having sufficient weight too'vercome thetension of the spring 111 and the pressure of the shoulder 108. Theplate 113 is below and in to the dis- Figs; 1, 3 and 6, fastened Spacedfrom the Ill) BEST Aylll tLE COF.

the path of movement of the arm 7 5, which is attached to the frame 26,and is also adapted to be depressed by the arm so as to release the disk107 from the plate 109, when said frame and receptacle -22 lowers, dueto the weightof a drink which has been discharge'dinto said receptacle.

Encircling the screw 1% is a convolute spring 115, one end of which isattached to the disk 107, its other end being attached to the plate 105.The tension of the spring 115 is such as to normally turn the disk 107clockwise, as viewed in Fig. 11, so as to bring the shoulder 108 intoengagement with the ratchet pawl or plate 109.

The disk 107 carries a pin 116 adapted to engage the upper edge of alever 117 adjacent to the forward end of the latter. Said lever 117v ispivoted on a shouldered screw 118 mounted in the plate 105, and it haspivoted to it near its rear end a link 118', which is pivoted to avertically movable contact bar 119, which is pivoted to a plate 120mounted on a block of insulation 121 fastened to the plate 105. Thelatter carries a plate 122 to which is secured a contact 123 adapted tobe struck by. a contact 124 carried by the contact bar 119, to close atthis point the motor circuit.

The lever 119 and plates 120 and 122 are. electrically conductive.

The circuit will be closed at the contacts 123 and 124, and the motor 70controlled thereby will continue to run until the disk 107 has beenreset to its initial position, shown in Fig. 11. -To reset said disk.107, there is mounted on a screw 126 a bell crank lever one arm 127 ofwhich has a slot through which extends a shouldered screw 128 mounted inthe disk'107. other arm 129 of the bell crank lever is forced forwardlysufficiently, the disk 107 will be retracted counter-clockwise to itsinitial position, shown in Fig. 11, where it When the the circuit, bymeans of the mechanism which has been described.

t The bell crank lever is operated to reset the disk 107 by the motor 70through the intervention of the following described mechanism.

Fastened to the shaft 62, which is rotated by power supplied from themotor 70 through mechanism already described, is a plate 130 whichcarries two diametrically opposite pins 131 and 132, which are adaptedto be consecutively brought into engagement with a, pin 133 mounted in aforwardly and baekwardly slidable plate 134 horizontally mounted on astandard 135, fastened to the plate 105, and between the plate 105 and aguide plate 136 mounted on the standard 135.

The shaft 62 is revolved counter-clockwise, as viewed inv Fig. 11, bythe motor, so that when the pins 131 and 132 enga e the pin 133, theplate 134 will be force forwardly so' as to have its forward end engagethe arm 129 of the bell crank lever, thereby swinging said lever. toreset the disk 107. After either of the pins 131 or 132 has passed, inthe revolution of the plate 130 which carries the pins, out ofengagement with the pin 133, the plate 134 will be retracted to itsinitial position, shown in Fi 11, by a coil spring 137, one end of whicis fastened to a screw I38 mounted in the standard 135, and the otherend of which is fastened to a screw 139 mounted in the plate 134 forwardof the screw 138.

When a purchaser places a proper coin in the coin receiver 3 and forcesthe coin into the chute 4, the coin in assin through the chute 4 willstrike an tip t e plate 113, Fig. 11, and will then ass the plate anddrop into the box 37, Flgs. 1 and 2. The tipping of the plate 113 willswing the pawl plate 109 away from the shoulder 108, upon which thespring 115 will revolve the disk 107 to release the lever 117, thusclosingthe motor circuit, as has been described, through the contacts123 and 124, and the bell crank lever will have its am. 129, broughtagainst the front end of the slide plate 134.

When the motor circuit is first closed, the shaft 62 and plate 130 willbe in the positions shown in Fig. 11, and the crank arm 61, whichoscillates the rock shaft 52, will be in the position shown in solidlines in Fig. 10.

VVl'ien the motor starts in its initial move ment, the shaft 62 willberevolved in the directionv indicated by the arrow, Fig. 11, and the pin132 will engage the pin 133, thus sliding the plate 134 to reset thedisk 107 and separate the contacts 123 and 124. At the same time therotation of the shaft 62 will start the roller 60 on its journey towardthe arm 58, Fig. 10.

A lever-145 pivoted on a horizontal axis on a standard 146, supported bythe bracket 56, has mounted on its front end a roller 147, which isadapted to run on the periphery of the cam disk 140, Figs. 2, 3 and 11,the

other end of the lever 145 being pivoted to the upper end of verticalmember. 148 carrying insulation 149. to which is attached a springcontact plate 150, mounted at one end on a block of insulation 151, Fig.3, supported b the bracket 56. The contact plate 150 is a apted to beforced by the lever 145 against a spring plate 152 mounted on aconducting plate 153, Figs. 3 and 11, which is mounted on the insulationblock 151.

The motor circuit is shown in Fig. 4. One brush of the motor 7 O isconnected by a conductor 154 with the feed wire 155 of a lighting orpower system. The other brushis j connected by a conductor 156 with thecontact carrying'plates 152 and 122. A conduotor 157 connects the returnwire 158 of plate 150 and When the contacts 123 and 124 are-in contactwith each other, the current'will pass from the feed wire 155,- thencethrough the conductor ,154, motor 7 0,- conductor 156, plate 122,contact 123, contact 124, bar 119, plate 120 and conductor 157 to thewire 158.

To keep the motor 7 0 supplied with current, after the contacts 123 and124 havebeen separated, and to enable the motor to cause the shaft 62 tomake a full half revolution, the contact plates 150 and 152 are broughttogether before the contacts 123 and 124 have been separated by the camsurface 141 engaging the roller 147 and swinging the'lever 145 to forcethe plate 150 against the contact plate 152. The motor 70 will thuscontinue running until the roller 147 enters the recess 144, at whichtime the 61 and 58 as'shown in dotted lines in Fig. 10.

- The roller 60in the turning of the shaft 62-will disengage from thearm 74, Figs. 3 and 10, thus permitting the receptacle 22 to drop to thefilling position shown in dotted "lines in Fig. 6. The valves 94 and 46will have been opened, thus permitting the syrup and carbonated water tobe discharged into the receptacle 22, the valve 7 9-will have beenclosed, Fig. 6, and the lever 17 will have been swung todrop a cup 15'to the position shown in F ig. 6, as has been described.

Whenenough carbonated waterhas been discharged into the receptacle 22to overbalance the weight 32, the frame 26 will lower, thus forcing'thearm 75 downwardly into engagement with the plate 113, Fig; 11, andcausing the said plate to move clownwardly, thus freeing the disk 107from the plate 109, upon which the contacts 123 and 124 will again bebrought into contact, as described, and the motor 7 0 will be started.

\Vhen the motor again starts, the shaft 62 will revolve the crank arm 61from the po sition shown in dotted lines in Fig. 10 to the positionshown in solid lines in that figure. In the continued revolution of thearm 61, the'roller 60 will first engage the crank arm 59, rocking itfrom the dotted position in'Fig. 10 to the position shown in solid.

lines, thus rocking the rock shaft 52 clockwise and effecting theclosing-of the valves 46 and 94 and the opening of the valve 79, therebyshutting, oif the discharge of carbonated water into the receptacle 22,and permitting the next chargeof syrup. to fill the casing 77 andcylinder 90, Fig. 8. r

After this has been done, the continued turning of the crank arm 61 toits initial position will cause the roller 60 to leave the crank arm 59and to engage the under side of the arm 74, of the receptacle 22, Fig.10, thus tilting the receptacle 22 to the discharge position shown inFigs. 3 and 6, and filling the cup 15 which is on the bottom of the cupreceptacle 16, Fig. 6. The purchaser of the drink then removes the cupthrough the opening 9, and returns the cup, after having drunk thecontents thereof, in to casing 1 through the opening 5.

When the contacts 123 and 124 are brought together the second't-ime, thefirst time having been effected by the coin, and the second time by thearm 75 of the frame 26, the roller 147 will pass out of the recess 144and onto the cam surface 142, thus tilting the lever 145 to bringthecontact plate 150 into contact with the plate 152 before the contacts123 and 124, areagain separated. The motor 70 will thus continue runninguntil the roller 147 passes again into the recess 143, upon which thespring contact plate 150 will separate from the contact plate 152, andthe motor 70 will stop, with the parts all returned to their originalinitial positions occupied by them before a. coinwas inserted in thechute 4. p

By the use of the cam controlledswitches, the operation of the motor 70and the proper positioning of the different parts at'the proper timesare positively and accurately effected.

In apparatus of this character it has been BEST AVAlLABLECGPY founddifiicult to always withdraw, from the supply, drinks of uniformquantity. It has also been found to be diflicult to always provide theproper and uniform quantity of syrup for a drink. With the use of themethod of obtaining the quantity of a drink -by the employment of acontrolling weight,

my apparatus will always provide drinks ofsubstantially uniformquantity.

'- uring of the syrup ingredient, the cylinder '90 is of relatively widediameter, and the passage 89, Fig. 8, is upwardly inclined therefrom.With this construction, when the valve 79 is open, the syrup will passdownwardly from the conductor 76 into the cylinder 7 8, thencedownwardly on the lower side of the passage 89 into the cylinder 90,

and the air, which is in the cylinder 90, will pass along the upper sideof the inclined passage 89 into the vertical cylinder 78, and from therewill bubble upwardly into the syrup tank 13 through the conductor'i'ti,so that no air pockets will form and the cylinder 78, above the loweredvalve 79, the passsage 89 and the cylinder 90, will completely fill withsyrup, thereby always measuring uniform quantities of the syrup contentof the drinks dispensed. Also by reason of the relatively large diameterof the cylinder 90 and the inclination upwardly of the passage 89, thecontents of syrup under the valve 79, when the latter is closed will bealmost instantaneously discharged into the receptacle 22 and replaced byair.

- As'shown in Figs. 1, 2 and 5, the ice tank 11 may be provided at itsbottom with avalved drain pipe 158,
